EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

This trend of increasing demand for higher octane gasoline is likely driven by changes in fuel requirements for light-duty vehicles (LDV) in response to increasing fuel economy standards, which will have widespread implications for future gasoline markets, according to EIA analysts.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). For instance, hybrid electric vehicles and diesel cars in the small (e.g., Renault Clio) and lower medium (e.g.,

New Delphi Technologies 500+ bar GDi system cuts gasoline particulate emissions by up to 50%, reduces fuel consumption

Green Car Congress

Reducing the number of exhaust gas particulates, including those smaller than 23 nm, will help manufacturers meet increasingly stringent future global emissions standards. Reducing engine-out emissions cuts tailpipe emissions in the crucial period before catalyst light-off and reduces the need for costly aftertreatment systems.

Continental introducing innovative annular catalytic converter for near-complete NOx reduction to meet RDE and SULEV 30 standards

Green Car Congress

Continental will present an innovative close-coupled annular catalytic converter that supports near-complete NO x conversion in downsized turbocharged gasoline engines at the 37 th Vienna Motor Symposium next week. On the US front, the LEV III SULEV 30 standards stipulate a 70% reduction in fleet-average nitrogen oxide emissions by 2025.

ACCESS project targeting 30% improvement in fuel economy and SULEV emissions in light-duty gasoline engine; multi-mode SI/HCCI combustion

Green Car Congress

Elements of the multi-mode combustion system include: Spark-ignited (SI) combustion with high compression ratio and high boost assisted by cooled external exhaust gas recirculation (EGR). Two-stage boost—a small supercharger for HCCI, and a regular turbocharger for downsizing.
